Artworks that money can't buy (but fixing the artist's boiler can)

If you believed you could never afford a Tracey Emin, think again. One of her works could soon be on your wall - but you might have to do her chores first.

Cash-strapped art lovers are being invited to bid for works in exchange for anything but cash via a "swap shop".

Browsers on website Art Barter can submit an offer for each item, from anything from fixing a boiler to second-hand goods, and the artist decides which proposal to accept.

The gallery features established and up-and-coming artists. The first 50 pieces will be displayed at the Rag Factory, Shoreditch, tomorrow night, and include contributions by Emin, Gavin Turk, Gary Hume and Boo Saville.

For the opening lots, there is a catch: the works will be offered anonymously - so bidders will not know whose art they are getting until they buy it.

Art Barter was the idea of London curators Lauren Jones and Alix Janta. Ms Jones said: "We want to make art available to a more diverse crowd, not just people with disposable income."

She said tomorrow's sale would "create a gamble" to make people value the art for what it really is. "We've got a couple of chefs coming who could cook an artist dinner. Some people might have a holiday home they are not using, or there might even be a plumber who could offer their services."

After tomorrow's event the website will go live for bids until Sunday, when the identity of the artists and winners of each lot are revealed.
